实验环境：POI3.7+Word2007
Word模板：
替换后效果：
代码：
1、入口文件
public class Test {
public static void main(String[] args) throws Exception {
Map<String, Object> param = new HashMap<String, Object>();
param.put("${name}", "huangqiqing");
param.put("${zhuanye}", "信息管理与信息系统");

param.put("${date}", new Date().toString());
Map<String,Object> header = new HashMap<String, Object>();
header.put("width", 100);
header.put("height", 150);
header.put("type", "jpg");
header.put("content", WordUtil.inputStream2ByteArray(new FileInputStream("c:\\new.jpg"), true));
param.put("${header}",header);
Map<String,Object> twocode = new HashMap<String, Object>();
twocode.put("width", 100);
twocode.put("height", 100);
twocode.put("type", "png");
twocode.put("content", ZxingEncoderHandler.getTwoCodeByteArray("测试二维码,huangqiqing", 100,100));
param.put("${twocode}",twocode);
CustomXWPFDocument doc = WordUtil.generateWord(param, "c:\\1.docx");
FileOutputStream fopts = new FileOutputStream("c:/2.docx");
doc.write(fopts);
fopts.close();
}
}
2、封装的工具类WordUtil.java

3、重写的类 CustomXWPFDocument
